  # IronOCR Visual C++ Redistributable Setup Please ensure that the latest version 2015-2022 of Microsoft Visual C++ Redistributable for Visual Studio is installed on the target machines. This is a required system component on Windows operating systems to run IronOCR and many other modern pieces of software reliably. ## Install Visual C++ Runtime for Windows [Download and run the installer](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170) from the official Microsoft support CDN. - **32-bit machines** require the x86 version only. [Download x86 from Microsoft](https://aka.ms/vs/17/release/vc_redist.x86.exe). - **64-bit machines** require both the x86 and x64 versions. [Download x64 from Microsoft](https://aka.ms/vs/17/release/vc_redist.x64.exe). - Ensure you're using the latest version: 2015-2022. For our "SaaS/OEM Redistribution" customers, one big advantage of installing the C++ runtime is that it can be packaged and distributed as part of an MSI or Executable program installer. ## Alternative Approach: Windows Update Some users prefer to get a successful fix by installing the [Windows Update for Universal C++ Runtimes on Windows](https://support.microsoft.com/en-us/topic/update-for-universal-c-runtime-in-windows-c0514201-7fe6-95a3-b0a5-287930f3560c). This approach is recommended by Microsoft for older operating systems such as Windows Server 2012, Windows 8, and Windows Vista.
